  • Lelit PL042EMI pressure only reaches 4bar

    It started happening today; the pressure only reaches 4 bar, instead of its usual 8 bar.

    I have tried adjusting the grind from the usual setting of 2.2 on the built-in grinder, all the way through to 5, with no effect.

    Suggestions please.

    What does it do with a blind filter in?

      Many thanks, I don't know why I didn't think of that 😐

      Pressure comes straight up to 9 bar. So that would indicate that the beans aren't being ground fine enough?

        I would agree, finer grinding needed

      So being that I haven't changed the grinder settings, and only tried changing them to finer today, after the issue appeared, this would suggest an issue with the grinder itself then?

        Don't rule out the coffee. Has it changed, new bag, different blend, etc. Lower amount of coffee?

      About 1/3rd of the way through a bag. Wife really likes Aldi's Lazzio Medium Roast coffee beans. Same amount: 18g for 2 cups, with 50g poured (25g / cup).

      I'll try another bean to see if that makes a difference.

        I was going to make a joke about 'you aren't using Aldi coffee' ! Try 250 grams fresh from a local roaster, cheaper than getting someone to look at your grinder.

        You might just have an older bag

        They can drop off pretty sharply sometimes, especially once opened. What's the roast date? (In YYMMDD below the expiry date on the side of the bag)
    Working...
